Harlan was in a car with four other people who police said met near Bowie High School, along the 2100 block of Highbank Drive, for a fight just before 3 p.m. July 27.

Detectives said several people in two cars agreed to meet near Bowie High School to engage in a physical fight. Five people were in the first car that arrived. The second car arrived and began to drive recklessly on the roadway in front of the school. At one point, Sims’ car started accelerating toward the car with five people in it. Investigators believe as the occupants were trying to exit the car and flee to safety believing the car they were seated in might be struck, Sims’ car swerved and struck Harlan on the roadway.
